Title: Improvements in and relating to shock-absorbing mechanism for typewriting machines
IPC: B41J19/10
Filed: 1935-01-18
Abstract: 433,921. Typewriters. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Underwood Elliott Fisher Co.; 342, Madison Avenue, New York, U.S.A.) Jan. 18, 1935, No. 1784. [Class 100 (iv)] Carriage - retarding devices.-In arrangements for arresting the carriage at the end of the return movement comprising shockabsorbing mechanism for gradually resisting movement beyond the marginal position, and shock-absorbing mechanism for resisting movement back to the marginal position, the same mechanism is employed for resisting both movements. 'In the arrangement shown in Fig. 1, a type-carriage 1 running on rails 3 is drawn towards the right-hand for letterspacing by means of a spring drum and is controlled by means of an escapement wheel which is mounted on the type-carriage and is geared to rack 5, a margin stop 4 for limiting return movement of the type-carriage being adjustably mounted on the rack. The rack is now mounted to move longitudinally on blocks 18 on the frame 3, and is associated with a dashpot 23, Fig. 3, comprising a piston 30 mounted in a cylinder 29 formed with ports 40, 33. The port 33 is closed by means of a disc 34 carried by an adjustable spring 35. The port 40 is so disposed that the part a of the cylinder is of greater volume than the part b. The piston-rod 31 is connected to a lever 20 engaging a pin 28 on the rack, the pin being adjustable by means of a nut 25 co-operating with a threaded rod 27 carrying the pin. Normally the rack abuts on an adjustable stop 60, and the piston is at the right of the port 40. When the type-carriage is returned, an abutment 6 thereon engages the margin stop, the rack is moved to the left, the piston moves past the port 40, and the rack and type-carriage are gradually arrested in over-margin position by the gradually increasing back-pressure of the air in the part a of the cylinder. The compressed air and the spring drum are then effective to return the rack and type-carriage quickly to normal position, as determined by the stop 60, the final part of the movement being abruptly cushioned by compression of air in the part b of the cylinder. The dashpot 23 may be replaced by a liquid dashpot consisting of a cylinder, and a piston resting on a spring and formed with a small throughport. Specification 411,278 is referred to.

The cups may be plated or enamelled. The transverse braces consist of wood or plywood discs 24 placed at the cup joint and also between the joint and the ends of the cell. The longitudinal braces consist of a plywood cylinder fitting the metal cups or internal solid or tubular members 26 of plywood. The cells may be placed under internal pressure. The spacers 8 consist of sponge rubber with impervious rubber skin 10 or hollow inflated rubber cylinders. The conducting wires 12 surround the cells or a rubber sleeve 16 enclosing the cells and have a rubber sheath 14. Specifications 585, 786 and 587,349 are referred to.

Abstract: 365,780. Prizing-tools for lubricating springs. NUNN, H. L., Ecila, Sheaf Lane, Sheldon, near Birmingham. Jan. 20, 1931, No. 1829. [Class 12 (ii).] A prizing-tool for leaf springs comprises a frame 1 having limbs 2, 9 carrying opposed wedge-shaped abutments 3, 15, the abutment 15 being adjustable while the other is formed with passages 8 or a slit through which grease. can be injected between the leaves, and a plate 17, which may have a facing of felt or the like, is carried by the abutment 15 so as to seal the adjacent edge of the spring against egress of grease. The abutment 15 is formed on a pin carried by a stem 14 which is adjustably screwed into a plunger 13 slidable in the frame under the action of a cam 12 secured on a spindle 11 which is mounted in a bifurcated lug 10 on the arm 9 and on which a lever is removably carried. The plate 17 is acted on by springs 19 fixed to the frame so as to maintain the plunger 13 in contact with the cam, but in a modification the springs are dispensed with and the plate carries pins engaging holes in the frame. The passages 8 in the abutment 3 diverge from a chamber 6 in the frame closed by a plug 7, the chamber communicating through a duct 4 with a nipple 5 adapted to be supplied with grease by a gun or other force-feed device. The supply from the nipple may be controlled by a manually-operable valve. The limbs 2, 9 may be separately fixed on a rod, one or both limbs being adjustable. Such rod may be hollow to form the barrel of a grease gun, the piston of which may be operated by a screw or actuated from the cam 12.

Title: Process for the preparation of rapidly hardening castable phenol-formaldehyde resins and castings produced therefrom
IPC: C08G8/00
Filed: 1949-01-27
Abstract: Selenium dioxide is added to a coatable phenol-formaldehyde resin precondensed in alkaline medium whereby the hardening time thereof is shortened and castings produced therefrom are free from tension.  In examples: (1) phenol, 33 per cent formalin, ethanol and sodium hydroxide are heated, the mixture acidified to pH4 with monochloro-acetic and lactic acids and water is distilled off.  An aqueous solution of selenium dioxide is added to the resin which is then further freed of water and hardened; (2) the resin of example (1) is completely dehydrated, a mixture of equal parts of glycerol and selenium dioxide added and the resin hardened.  The Specification as open to inspection under Sect. 91 states that dioxides of metalloids from the sixth group of the periodic system may be added to the castable resin and in an example sulphur dioxide is led into the resin of example (1).  This subject-matter does not appear in the Specification as accepted.

Abstract: 395,771. Fluid-pressure brakes. BROWN, D. F. and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Jan. 27, 1932, No. 2521. [Class 103 (i).] In a vacuum brake when train-pipe vacuum is reduced to a predetermined degree to apply the brake, communication between the lower and upper chambers of the brake cylinder 1 is cut off and the upper chamber and a vacuum reservoir 6 are connected, by a valve 17. This valve is controlled by a diaphragm 9 controlled by the vacuum in the train-pipe 8 and in the reservoir 6. On releasing the brakes the valve 17 connects the upper and lower chambers of the brake cylinder through restricted port 20, thus releasing the brakes at a vacuum less than the normal running value. The reservoir 6 is simultaneously cut off from the upper chamber of the brake cylinder. A piston 21 on the stem of valve 17 gradually restricts communication between the chambers of the brake cylinder before this communication is cut off. The reservoir 6 communicates with the trainpipe through the non-return valve 15 of the usual release valve.

Abstract: 713,479. Pneumatic conveyers; unloading material from vehicles by fluidization. SMIDTH & CO. AKTIESELSKAB, F. L. Dec. 9, 1952 [Jan. 30, 1952], No. 2521/52. Classes 78 (1) and 78 (4) In means for discharging powdered material from a container by fluidising the material so that it flows downwards over a uniformly inclined porous bottom to an outlet, the gas flow through the bottom is greater at points remote from the outlet than at points nearer the outlet. The inclined container 2 has a porous bottom 9 of part cylindrical cross-section. The space below the bottom to which air is supplied by a blower 2' is divided by partitions 15, Fig. 3, into compartments 16, 17, 18. The blower is connected by a pipe 11 to a manifold 23 which is connected to the compartments by branch pipes 19, 20, 21. Apertured plates 22 in the branch pipes restrict the air flow so that the pressure in the compartment 16 is less than that in the compartment 17 which is itself less than that in the compartment 18. The bottom consists of zones 8, 9, 10, Fig. 4, each of which consists of a layer of felt 12, layers of canvas 14 and protective layers of wire netting 13. The number of layers of canvas increases from zone to zone so that the air flow is greater through the zone 8 and least through the zone 10. In a modification the nature of the porous bottom does not vary along its length, but each compartment is divided by cross-members into three, each of which is supplied with air from a common pipe through branches containing apertured plates. In another modification the bottom includes a layer of felt which tapers in thickness. In a further modification a bottom composed of felt and canvas is protected by perforated metal sheets, the air flow being determined by the spacing and sizes of the perforations. Specification 703,852 is referred to.
